      Marco Polo is a Near-Earth Object (NEO) sample return mission currently studied by the European Space Agency (ESA). The intention is to perform this mission in collaboration with the Japanese Aerospace Exploration Agency ...
    • Markov Modeling of Component Fault Growth Over A Derived Domain of Feasible Output Control Effort Modifications 

      Bole, Brian; Goebel, Kai; Vachtsevanos, George (Georgia Institute of Technology, 2012-08)
      This paper introduces a novel Markov process formulation of stochastic fault growth modeling, in order to facilitate the development and analysis of prognostics-based control adaptation. A metric representing the relative ...
